This invention relates to improvements in sprinkler taps.

There is a well-known type of tap known as a revolving nozzle tap in which a fixed spigot body has an annular seat to engage a stop-valve or jumper and said spigot body has an external screw-thread adapted to engage an internal thread on a rotatable faucet sleeve within which the stop-valve or jumper is axially movable so that manual rotation of said faucet sleeve tends to move said stop-valve or jumper to or from said seat. In a known modification of that type the hollow cylindrical spigot body contains a polygonal check-valve which when the faucet sleeve and stop-valve are removed from the spigot body, allows the check-valve to be closed against a seat in the spigot body.

It has recently become desirable to fit revolv ing nozzle taps with sprinkler nozzles and as is well-known a sprinkler nozzle sets up a back pressure within the body of the tap and in fact the rate of ilow through the sprinkler depends partly on the area of the sprinkler orifices and partly on the difference between the hydraulic pressures at the inlet and outlet of the stopvalve.

The supply pressure may vary very considerably at different tap positions. Thus in a bungalow or other one-story building thesupply pressure might be say 5 lb./in.2 whereas in a high building with reservoir or cistern near the top the supply pressure at a ground floor tap might be 100 lb./in.2 and as sprinkler taps are frequently allowed to dow for considerable periods (e. g.

the tap may be left on above an unplugged trough or basin), it becomes important for` reasons of economy, to regulate the pressure difference at the stop-valve,

This invention consists in the combination with a sprinkler tap and a stop-valve which can be opened or closed in the tap body, of a conduit from the supply furnished with a readily accessible adjusting screw to regulate the flow towards the tap.

In a particular form of this invention as applied to a revolving nozzle tap, the sprinkler is secured (e. g. by screw engagement) to the ro tatable faucet sleeve and at a convenient point in the supply conduit e. g. immediately in advance of the tap an adjusting screw is provided. The adjusting screw may be provided with a cover cap.

In revolving' nozzle taps of the general type referred to above, it is customary to seal the top of the rotary faucet sleeve by a nut. In a preferred form of the present invention where a sprinkler tap may set up a back pressure within the body,

' a gland packing (such as one or more deformable Washers of rubber or synthetic rubber or asbestos composition) may be used to ensure the sealing of the rotary faucet sleeve in relation to the xed spigot body.

The nature of this invention and the manner in which it is performed will be appreciated from the following description of an example reference being made to the accompanying drawings in which:

Figure 1 is a side elevation partly in section of a sprinkler tap associated with a revolving nozzle tap, and

Figure 2 is a central section of a conduit from the water supply furnished with a readily acccssible adjusting screw to regulate the: flow towards the tap.

Referring to Figure l, the stop valve is of the general type in which the fluted member which supports the stop valve is slotted in an axial direction and has a taper engagement with the faucet sleeve, the arrangement being such that when the iiuted member with the stop valve in place is forced home into its normal working position in the sleeve, consequent compression of the Iluted member causes the latter to embrace the depending stem of the stop valve so that the sleeve, the fiuted member and the stop valve with its stem are linked together during normal operation of the faucet sleeve and when the sleeve is removed bodily from the faucet. The cylindrical spigot body l2 (which is fixed) has a cylindrical valve passage I3 terminating in an annular seat I4 adapted to engage the washer of the stop valve or jumper I6.

` The jumper I5 has an axial jumper stem normally guided in the bore of the anti-splash iluted member I8. The spigot body is externally threaded at its lower part 2t. The rotary sleeve 2| is in the form of a sprinkler body and has an actual sprinkler 22 at its lower end. This sprinkier body which constitutes a faucet vsleeve has a main internal thread 23 arranged to engage the external thread 20 at the lower part of the spigot body and the rotary faucet sleeve or sprinkler body 2| has a capstan handle 24. The cylindrical spigot body I2 also contains a check valve having a tailpiece 25 which normally makes contact with the jumper I6. The faucet sleeve 0r sprinkler body 2| is normally sealed at its upper end by a securing nut 26 and when it is desired to remove the sleeve 2|, fluted member 8 and jumper I6 from the spigot body |2, the securing nut 26 is removed and the normal supply pressure and the action of gravity cause the check valve to close on its seat immediately above the stop valve passage I3 so that Water from the supply cannot escape.

The cylindrical spigot body isl directly in communication with the passage 21 in the body 28 of the valve as a whole and it is a feature of this invention that at a convenient point in the supply conduit 21, e. g. immediately in advance of the tap, an adjusting screw 29 is tted and the adjusting screw is provided with a cover cap 30.

What I claim is:

A faucet assembly including a relatively fixed body portion, a rotary control nozzle furnished With a sprinkler exit, an external thread on said body portion coacting with an internal threadon said rotary control nozzle, a jumper carried by said rotary control nozzle and a coacting seat on said fixed body portion, a stop valve within said fixed body portion controlled by said rotary control nozzle and an adjustable pressure regulating device in said xed body portion in the line of ow prior to said stop. valve.A
